prevention of hypoglycemia among diabetes patients admitted to internal medicine departments with nutritional care

Conditions: Hypoglycemia; Malnutrition; Diabetes

Summary: this is a prospective randomized study to evaluate the efficacy of nutritional intervention for the prevention of hypoglycemia among diabetes patients with low albumin level that are admitted to internal medicine units, regardless of the reason for admission. all patients suitable for participation in the study will be asked to participate and be randomized to the interventional arm or the control arm. after admission to the internal medicine unit, eligible patients will be asked to participate in the study. after signing an informed consent form, patients will be randomized to the treatment or control arms. for patients allocated to the treatment arm, the physician in charge will prescribe 2 portions of glucernatm per day as part of the treatment protocol. the nurse in charge of the patient (at either the morning or evening shifts) will make sure the patient is receiving and consuming the ons. for every patient included in the interventional arm, 2 bottles of glucernatm will be supplied to the patient, one at 08:00 with the morning medications, and one at 16:00 with the evening medications. for clarification purposes, the glucernatm will be supplied on top of the designated meal plan, as "over-feeding". evaluation of adequate ons consumption will be performed 2-3 hours after the dispensing of the ons (at 10:00-11:00 and 19:00-21:00), and the amount consumed will be documented. patients in the control arm will receive no oral nutritional supplementation, and their caloric intake will be composed of the food supplied by the hospital. other analysis will be considered usual care. additional diet consultations as requested by the medical staff will constitute usual care, and the patient will continue the study. the duration of ons treatment will be the entire length of hospital stay. upon discharge, a recommendation to continue nutritional care will be added to the patients' discharge letters but no oral nutritional supplement (ons) will be prescribed or dispensed. following discharge, a 30-day follow-up call will be made to ascertain whether the patient is alive, whether the patient was re-admitted or re-hospitalized, and the usage of ons prescribed by the family/general practitioner that was consumed after the hospital discharge.

1.2 definitions: a. hypoglycemia: a blood glucose level of 70 mg/dl or lower, regardless of symptoms b. hypoalbuminemia: albumin level below 3.5 g/dl upon admission to the hospital c. adequate nutritional consumption: the consumption of at least half of the oral nutritional supplements d. target population: diabetes patients admitted to internal medicine units that have baseline hypoalbuminemia upon admission. this is a prospective randomized study to evaluate the efficacy of nutritional intervention for the prevention of hypoglycemia among diabetes patients with low albumin level that are admitted to internal medicine units, regardless of the reason for admission. all patients suitable for participation in the study will be asked to participate and be randomized to the interventional arm or the control arm. after admission to the internal medicine unit, eligible patients will be asked to participate in the study. after signing an informed consent form, patients will be randomized to the treatment or control arms. for patients allocated to the treatment arm, the physician in charge will prescribe 2 portions of glucernatm per day as part of the treatment protocol. the nurse in charge of the patient (at either the morning or evening shifts) will make sure the patient is receiving and consuming the ons. 2.3 study population: all adult patients admitted to internal medicine units of the wolfson medical center that will participate in the study. the admission to the unit can be either from the er or as a transfer from other departments in the hospital. inclusion and exclusion criteria specified above. drop-out criteria a. patients in need of mechanical nutritional support (same as above), as a complication of the hospitalization. b. patients that have a designated nutritional care program recommended by the unit's dietician that includes ons. for clarification purposes, fortification of the meal plan by changing the food items (i.e. low sugar items, high fat/protein and or etc.) will not be considered a drop-out indication, as long as ons are not part of the intervention. c. patients with undocumented albumin level for the first 72 hours of the hospitalization to the internal medicine unit. d. patients that were enrolled in the study but were transferred from the internal medicine department to a different unit of treatment during the hospitalization. for clarification purposes, transfer to interventional radiology, interventional cardiology or any other units for a specific procedure is not considered a dropout criteria, as long as the patient is back in the internal medicine unit within 24-48 hours of the procedure. 2.4 interventional program interventional arm a. for every patient included in the interventional arm, 2 bottles of glucernatm will be supplied to the patient, one at 08:00 with the morning medications, and one at 16:00 with the evening medications. for clarification purposes, the glucernatm will be supplied on top of the designated meal plan, as "over-feeding". b. evaluation of adequate ons consumption will be performed 2-3 hours after the dispensing of the ons (at 10:00-11:00 and 19:00-21:00), and the amount consumed will be documented. c. patients in the intervention arm that will be unwilling to consume the ons will not drop out of the study, but rather the follow-up will continue as usual (itt design). the ons will be offered every day, twice a day, regardless of the answer and the amount consumed. for patients that decline, the reason for lack of consumption will be documented. d. the duration of ons treatment will be the entire length of hospital stay. upon discharge, a recommendation to continue nutritional care will be added to the patients' discharge letters but no ons will be prescribed or dispensed. control arm a. patients in the control arm will receive no oral nutritional supplementation, and their caloric intake will be composed of the food supplied by the hospital. other analysis (i.e. malnutrition screen, blood tests etc.) will be considered usual care. additional diet consultations as requested by the medical staff will constitute usual care, and the patient will continue the study, as long as no additional ons are prescribed as part of the treatment plan (criteria 2 of the drop-out criteria). b. upon discharge, a recommendation to continue nutritional care will be added to the patients' discharge letters but no ons will be prescribed or dispensed. post discharge, all patients following discharge, a 30-day follow-up call will be made to ascertain key points: a. whether the patient is alive b. whether the patient was re-admitted or re-hospitalized c. usage of ons prescribed by the family/general practitioner that was consumed after the hospital discharge. 3.1 informed consent the study will seek the approval of the local institutional review board (irb) as an interventional study. all patients participating (either in the treatment or control arms) will sign an informed consent upon study inclusion. 3.2 data recording for each patient, a paper case report form (crf) will be produced. the patient data recorded in the crfs will include the following information a. demorgaphic data a.1. age, sex, marital status b. reason for admission, one or more of the following (multiple selection) b.1. infection
